Nope. The relationship between the alleles is relative. When comparing two alleles, the more dominant one is given the capital letter.

Codominant Morph:
Super Pastel = PP
Pastel = Pp
Normal = pp

Because the Pastel gene is only somewhat dominant to the Normal gene. That is why you get partitial expression (codominance).

Now, when you look at a simple recessive morph such as Albino, the morph gene is recessive to the normal gene.

Recessive Morph:
Normal = AA
Het. Albino = Aa
Albino = aa

And, just to be clear, here is an example of a dominant gene. In this case, the normal gene is completely recessive to the morph gene.

Dominant Morph:
Champagne = HH
Champagne = Hh
Normal = hh


Once again, this isn't my opinion or interpretation, this can be found in any bio textbook.
